RISC-V: Cleanup redundant reduction patterns after refactor vector mode
This patch cleanups redundant reduction patterns after Juzhe change vector mode
from fixed-size to scalable-size. For example, whether it is zvl32b, zvl64b,
zvl128b, RVVM1SI indicates that it occupies a vector register. Therefore, it is
easy to map vector modes to LMUL1 vector modes with define_mode_attr without
creating a separate pattern for each LMUL1 Mode. For example, this patch can
combine four patterns (@pred_reduc_<reduc><VQI:mode><VQI_LMUL1:mode>,
@pred_reduc_<reduc><VHI:mode><VHI_LMUL1:mode>
@pred_reduc_<reduc><VSI:mode><VSI_LMUL1:mode>,
@pred_reduc_<reduc><VDI:mode><VDI_LMUL1:mode>) to a single pattern
@pred_reduc_<reduc><mode>.
